Abstract: In order to get the state of particles and the reaction process in the electrolyte during electrodeposition clearly, the lotus leaf-like superhydrophobic film is prepared on the surface of aluminum alloy by electrodeposition, in which the contact angle reach 159.3∘. According to contact angle and scanning electron microscope results, the crystal water in the electrolyte system plays an important role in the deposition process. The existence of crystal water can promote the ionization of Ce3+ and form the carrier system effectively. The composition of the film is cerium stearate, which shows multilayer growth. The electrochemical impedance spectra results show good corrosion resistance and application value.
